For people in southern China, the so-called "return to the south" is often encountered in spring. This special weather can not only bring a lot of inconvenience to people's lives, but also test people's wisdom in life. So, what exactly is Hui Nantian? Should we open or close the windows in this weather? This article will elaborate on the causes, impacts and countermeasures of Hui Nantian to help you deal with this seasonal problem scientifically.
Hui Nantian usually refers to the phenomenon of the temperature warming up and the humidity rising suddenly in the spring every year. This is due to the fact that after the cold air goes, the warm and humid airflow is rapid, causing the temperature to rise, the air humidity to increase, and some cold objects are prone to water droplets after encountering the warm and humid airflow. The phenomenon of returning to the south is more serious in the south, which is related to the fact that the south is close to the sea and the air is humid. When "Hui Nantian" appeared, the air humidity was close to saturation, the walls and even the ground would be "water", and there was a wet scene everywhere, and the air seemed to be able to wring out the water. And the dense fog is the most characteristic appearance of "returning to the southern sky".
Returning to Nantian has brought a lot of inconvenience to people's lives. Slippery floors can easily lead to falls, clothes are not easy to dry, wooden furniture swells when damp, and electrical equipment can also malfunction due to moisture. In addition, a humid environment is also conducive to the growth of microorganisms such as mold and bacteria, which poses a potential threat to human health.
In the face of returning to Nantian, many people hesitate between opening the window and closing the window. In fact, the answer to this question is not set in stone, but needs to be judged on a case-by-case basis.
1.Close the windows at the right time
Before and at the beginning of the return to the south of the sky, closing the windows at the right time is the most effective way to prevent moisture. Since the weather is characterized by a large temperature difference between morning and evening and heavy fog, doors and windows should be closed before the fog comes, especially those facing south and southeast. This prevents warm and humid air from entering the room, reduces the indoor moisture content, and keeps the room relatively dry.
2.Open the window to a limited extent
However, keeping doors and windows closed for long periods of time can also lead to poor indoor air circulation, which is not good for health. Therefore, at noon or in the afternoon when the sun is better and there is less fog, the windows can be opened for a short period of time. At this time, the temperature and humidity outside are relatively high, but it is still necessary to pay attention to control the window opening time to avoid the indoor humidity rising too quickly.
3.Use equipment such as air conditioners to dehumidify
In addition to adjusting the indoor humidity by opening and closing the windows, you can also reduce the indoor humidity with the help of air conditioners, dehumidifiers and other equipment. These devices are effective in removing moisture from the air, keeping the indoor environment relatively dry. However, it is important to note that the filter and water tank should be cleaned regularly when using these devices to avoid the growth of bacteria.
Spread the newspaper:It's good practice to spread newspaper on the floor and on the table to absorb moisture. Spread the used old newspaper on the floor and table, especially in places that are easy to get wet such as the doorway, and spread two more layers, so that it has a good moisture-proof effect on the interior.
Put dehumidifier:You can go to the supermarket to buy some dehumidifier and place it in all corners of the house and places with heavy humidity, which can effectively absorb water vapor, remember to replace it in time.
Light the candles:Lighting a candle prevents moisture from condensing, which reduces the humidity in the room. If you already have a musty smell in your home, you may want to choose a candle that contains natural plant essential oils, which will not only dry out the air, but also remove musty odors from the room.
Mop the floor with hot water and salt:This method can accelerate the evaporation of water, and after mopping the floor, spread some waste cardboard boxes or newspapers at the door of the house, so that the soles can reduce the amount of moisture brought in.
Lime moisture absorption:In small spaces such as toilets and bathrooms, you may wish to wrap quicklime in a cloth bag to absorb moisture. You can also poke a few holes in the laundry detergent bag and use the laundry detergent to absorb moisture.
